23 Claims.

This invention relates to lasting machines and is herein shown asapplied to a power-operated toe-lasting machine constructed generally asdisclosed in United States Letters Patent No. 2,324,509, granted on July20, 1943, on an application of mine, but modified in some respects inaccordance with later disclosures including that of a copendingapplication of mine Serial No. 134,041, filed on December 20, 1949. Itis to be understood, however, that in various novel aspects theinvention is not thus limited in its applicability.

The machine to which the invention is shown as applied is a machine inwhich various mechanisms are operated by fluid, preferably light oil,maintained under pressure in a manifold from which the fluid is admittedby valves to the different mechanisms, the fluid being thus maintainedunder pressure while the machine is in operation by a continuouslydriven pump and the maximum pressure in the manifold being determined bya spring-controlled relief valve. The machine includes a toe restarranged to engage a shoe on the top of the forepart to support the shoeagainst pressure applied on its bottom face, and also a heel rest forengaging the heelend face of the shoe and holding it against lengthwisedisplacement in a heelward direction in the lasting operation, the toerest and the heel rest being forced firmly against the shoe by the fluidpressure. While the pressure applied to the shoe by the toe rest or theheel rest should be sufficient to prevent any displacement of the shoe,it should not be great enough to mark the upper, the pressure which maybe safely applied depending somewhat upon the character of the uppermaterials. To meet different conditions the present invention providesmeans whereby the pressure of the fluid effective on either the toe restor the heel rest may be variably predetermined independently of thepressure effective on the other and independently of the pressure at thesource, i. e., in the manifold. For this purpose there is interposed ineach fluid line leading from the manifold to the means for operating thetoe rest or the heel rest pressurecontrolling mechanism including acut-off valve and a spring-controlled member movable in response to thepressure of the fluid effectiv on the toe rest or the heel rest to closethis valve and stop th how of the fluid when that pressure reaches apredetermined limit, the spring controlling this member being adjustableto vary that limit. This member is so arranged that any force applied tothe shoe in the lasting operation tending to press the shoe more firmlyagainst the toe rest or the heel rest only serves to hold thecorresponding cut-off valve more firmly closed, thus insuring that theshoe will be firmly held against any displacement.

The machine is provided with wipers which wipe the margin of the toe endof the upper inwardly over an insole on a last positioned bottom upward,and with upper-trimming means movable in a plane parallel to the topfaces of the wipers to remove from the margin of the upper supported inoutspread position on the wipers all but the outer layer of the uppermaterials before the upper is thus wiped inwardly over the insole.Preparatory to the upper-trim ming operation a wiper support is movedupwardly to carry the wipers to a predetermined height relatively to theedge of the insole While the upper is being pulled outwardly over thewipers by grippers engaging the margin of the upper materials, theupper-trimming means being moved downwardly into proper relation to thewipers for the trimming of the upper as above described. After thetrimming of the upper the wiper support is moved downwardly and thenmoved upwardly a second time, coordinately with a second pull applied tothe upper by the grippers, preparatory to the wiping of the margin ofthe upper inwardly over the insole. Heretofore the wipers have beenpositioned at such a height in the upper-trimming operation that amargin of about an eighth of an inch is left on the trimmed layers ofthe upper materials to overlap the bottom face of the insole when theupper is wiped inwardly over the insole, this being the height at whichthe wipers are also positioned by the second upward movement of theWiper support for the wiping of the upper inwardly over the insole. Somemanufacturers, however, would prefer that a margin of somewhat greaterwidth be left on the trimmed layers of the upper materials to overlapthe insole, but if the wipers are positioned at the height required forthis result in the upper-trimming operation, they should not be moved tothe same height by the second upward movement of the wiper support,since in that case they would be too high to act most effectively on thupper in wiping it inwardly. In View of these considerations the machineherein shown is provided with means whereby the wipers may be moved to agreater height by the first upward movement of the wiper support than byits second upward movement, the limit of the downward positioningmovement of the uppertrimming means being correspondingly changed. Inthe machine shown both upward movements of the wiper support areeffected, as heretofore,

shifting of the link the second upward movement.

of the support is terminated short of the limit of its first upwardmovement. For thus shifting-the link there is provided a latch which isidle in the first upward movement of the'wiper support but is thereaftermoved into positionito cause itto shift the link in response toth secondupward movement of the support; To=cause thewipers alternatively to bemoved, if desired, to the same height by the first upward movement ofthewiper support as by its second movement, so that a margin ofless'width Will-be left onthe-trimmed 'layers' ofthe upper-materials tooverlap the-insponse to each upwardmovementof the support,

wipes the upper around the toe end "of the last heightwise -of the lastwhile the upper is held under tension by the upper-gripp'ingand pullingmeans.- It-will be evident that when the wiper support is moved upwardlya greater'distance'the first time in the manner above described, the'toeformer has a more extendedwiping action on the upper in the vicinity ofthe edge of the :insole. This has been found to contributeto thesmoothness of the upper adjacent to the edge of-the insole in thecompleted shoe and is 'accordingly ad- 'vantageous' regardless ofconsiderations relating to the trimmingof the upper.

'In general accordance with the disclosure' of Letters Patent No.2,l'79,5'75, granted onAugust 23, 1949, onan 'a-pplicationof mine;theabovementioned pin-and-slot connections between the wiper support andthe-pistonswhich operate it permit the support to be moved fartherupward relatively to the pistons against the *force of gravity inresponse to resistance of the upperto the inward movements of the wipersover the insole. This prevents 'the wipers from' acting too severely onthe margin of the upper as they otherwise might under some conditions.:After the 'wipers'have wiped the upper inwardly over the insole thepistonsare operated to increasetheir downward pressure on the upper andare then returned to their upper limitsofmovement to relieve thepressure. In accordance with a further feature the invention providesmeans'whereby the margin'of the'upper is substantially released at thistime from any pressur'e-of'the wipers thereon. In the construction shownthis is accomplished by substantially eliminating at the required timelost motion between'one ofithe pistons and the wiper support, sothatsuch' movement as the pistonreceives in relieving'the pressure'ofthewipers on the upper will be transmitted .to the support to raise thewipers. More 4 particularly, the Wiper support carries a member which,as the pistons are moved downwardly to increase the pressure of thewipers on the upper, is moved by a spring into such relation to a pincarried by one of the pistons as to transmit movement from the pin tothe wiper support upon upward movement of the piston. The means for thussubstantially releasing theishofe from downward pressure'of the wipersthereon is of special advantage in the machine herein shown by reason ofthe presence of the previously mentioned ipressure-controlling mechanismin the fiuid line leading to the toe rest. As previously explained, thismechanism'dncludes a cut-off valve which is held more-"firmly closed byany increase in downward pressure applied by the shoe to the toe rest;The timing of the machine is such as to call for release of the toe restby the fluid acting th'ereon to cause it to return to its initialposition prior to the retractive movements of the wipers-from over theshoe; and accordingly the provision of the above-describedmeans--for-'substantially releasing the toe end of the shoefrom thepressure of the wipers thereon while-the wipers are over the shoeinsures that the abovementioned cut-on valve will not be prevented fromopening at the time inthe cycle" when: the return of thetoe restis'supposed to take'place."

The above and other features of the invention,

including various novel details of construction and combinations ofparts, will now bemoreparticularly described with reference totheaccompanying drawings and thereafter pointedout in the claims.

a In view of the above-mentioned prior disclosures, only as much of themachine will be herein described in detail as is necessary for anunderstanding of the invention. The shoe is presented to the machinebottom upward and ispositioned heightwise by engagement of a shoe-=restplate 2 (Fig. 8) with the bottom of the forepart of the insole. It isclampedagainst this plate substantially at the beginning of theoperation of the machine by an upwardly 'movable toe rest F 4 whichengages the shoe underneath on the top of the forepart and isforcedfirmly against the shoe by a fluid-operated piston 6 (Fig. 11)movable in' a cylinder 8. Operating fluid, preferably light oil, underpressure is admitted to this cylinder through a pipe line [0 from amanifold [2 in which the fluid is maintained under pressure during theoperation of the machine by a pump [4. The pump receives fluid through apipe [6 from a sump I8 and forces it into the manifold through a pipe20, the maximum pressure of the fluid in the manifold being determinedby a spring-controlled relief valve 22 past which the excess fluidreturns to the sump through a pipe 24. Admission of the fluid from themanifold to the pipe line It leading to the cylinder 8 is effected by anautomatically operated valve 26 which, near the end of the cycle, ismoved to exhaust position to release the fluid from the cylinder 8 andpermit it to return to the sump. In addition to the toe rest 4 themachine includes a heel rest 28 for engaging the heel end face of theshoe to assist in preventing its lengthwise displacement in a heelwarddirection in the lasting operation, this heel rest being applied to theshoe and forced firmly against it by a piston 30 movable in a cylinder32 to which fluid is admitted through a pipe line 34 from the manifold12 under control of a valve 36 operating similarly to the valve 26. Theheel rest is supported on a carrier 38 which is mounted for swingingmovement about a rod 40 and is connected to the piston 30 by a link 42.

The pressure applied by the toe rest 4 to the shoe should be sufficientto support the toe end of the shoe against any downward movement inresponse to pressure on the bottom of the shoe in the lasting operation,and yet must not be great enough to mark the upper. Similarly, thepressure of the heel rest 28 on the heel-end face of the shoe should besuflicient to insure against any lengthwise displacement of the shoe ina heelward direction by the lasting means, and yet must not be so greatas to mark the upper or to damage a hinge last. The pressure which maybe applied by either the toe rest or the heel rest without marking theupper will depend to some extent on the character of the uppermaterials.

In view of these considerations, the machine herein shown is providedwith means whereby the pressure of the fluid effective on either the toerest or the heel rest may be variably predetermined independently of thepressure of the fluid effective on the other and also independently ofthe pressure of the fluid effective to operate other parts of themachine. For this purpose there is interposed in each of the pipe linesIt and 34 (Fig. 11) a pressure-controlling device 44, the parts of bothdevices being identical and identified by the same reference characters.Each device includes a casting 46 having in one end thereof a chamber 48to which fluid is ad mitted from the manifold I2. Also formed in thecasting is a cylinder 50 in which is mounted a piston 52. Between thechamber 43 and the cylinder 50 the casting 46 has formed thereon aninwardly extending annular flange 54 which provides a passageway throughwhich the fluid may flow from the chamber to the cylinder. A stem 56extends from the piston 52 through this passageway but is smaller thanthe passageway to permit the flow of the fluid, and fast on the end ofthis stem is a cut-off valve 58. Confined between the piston 5?. and anabutment 58 is a spring 62 which tends to move the piston toward theflange 54, its movement in that direction being limited by engagement ofa spider 64 formed on the stem 56 with the flange. The spring 62 isadjustable to vary its compression by a screw 66 which is threaded inthe plug 68 in the casting 46 and engages the abutment 60. A port 70 inthe casting provides open communication between the portion of thecasting in which the spring 62 is mounted and the atmosphere. Anotherport in the casting provides communication between the cylinder 50 andthe portion of the pipe line H) or 34 leading to the cylinder 8 or 32.With the parts positioned initially as shown the valve 58 is open andpermits fluid to flow from the chamber 48 to the cylinder 56 and thenceto the cyilnder 8 or 32 when the corresponding valve 26 or 36 isoperated. As soon as the fluid pressure effective on the toe rest or theheel rest becomes great enough to overcome the force of the spring 62the piston 52 is moved into position to seat the valve 58 on the flange54 and thus to stop the flow of fluid from the chamber 48 to thecylinder 50. In this manner the pressure of the fluid effective on thetoe rest or the heel rest is limited, in accordance with the adjustmentof the corresponding spring 62, independently of the pressure of thefluid effective on other parts of the machine, and it will also beevident that the pressure applied by either the toe rest or the heelrest to the shoe is thus variably predetermined independently of thatapplied by the other. It will be further evident that any force appliedto the shoe in the lasting operation and tending to press the shoe moreflrmly against the toe rest or the heel rest only serves to hold thecorresponding valve 53 more firmly closed by reason of the increase inthe pressure of the fluid effective on the corresponding piston 52, thusinsuring that the shoe will be firmly held against any displacement.When the valve 26 or 36 is moved to exhaust position the release of thepressure in the chamber 48 which results from such movement of the valvecauses the spring 62 to move the corresponding valve 58 to open positionand thus to release the fluid in the cylinder 8 or 32.

In general accordance with the prior disclosures the machine is providedwith a toe-end gripper 12 which grips the margin of the upper at the endof the toe and with opposite side grippers, not herein shown, which gripit at the sides of the toe, the end gripper and the side grippers beingmovable respectively in directions mainly lengthwise and widthwise oithe shoe to apply a pull to the upper. The machine also includes a pairof toe-embracing wipers 14 (Figs. 2 and 8) for wiping the margin of theupper inwardly over an insole on the last and a toe former 16 (Figs. 2,3 and 8) positioned immediately under the wipers for wiping the upperaround the toe heightwise of the last, the toe former and the means forcontrolling it being constructed substantially as disclosed in thepreviously mentioned application. As disclosed in detail in LettersPatent No. 2,324,509, the wipers are mounted on wiper holders [8 (Figs.2 and 3), these wiper holders being mounted on a wiper carrier 85movable in directions lengthwise of the shoe relatively to a member 82on which it is mounted and which may be termed a wiper support. Thewiper carrier is moved forwardly lengthwise of the shoe byfluid-pressure means and in response to such movement of the carrier thewiper holders 18 and the wipers are swung about a vertical axis to causethe wipers to close inwardly over the insole widthwise of the shoe.

The wiper support 82 is mounted as heretofore for upward and downwardmovements and .last .in response tothe upward movement oftheisupportwhile'thegrippers are applying their ipull' to the upper. Inthus pullingthe upper the grippersin'thefirst instance griptheseverallayers of upper materialsjjusually =including at .lea'st'ax toe boxand'salining in: additionto the outerlayer, and'at the end of the upwardmove- ;mentzof' the wiper support they hold the marginal portion of theupper outspread over the top'ffacesof the wipers. Thereafter the upperoperated upon by trimming meanse l (Fig. l) to remove from its margin:over the wipers all .but'. the :outer layer of the: upper materials, asillustrated in'Fig. 8,- the, grippers releasing the upper prior to thecompletion of the uppertrimming operation. This upper-.trimming-meansincludes an end knife 85 mova'ble lengthwise of the shoe in a rearwarddirectionirom. an initial positionovervthebottompf theeshoe and a pairof side knives 88- movable outwardly widthwise of the shoe from overthe-bottom'of the shoe. The endknife is-carried by an arm 90 which isswung downwardly-to position its cuttingedge in thesamel-plane as theedges of the side knives 88 beforeit becomes effective on the upper, andassociated with each side knife is a vertical knife-92- arrangedtodetach from the rest of the upper the strip resulting from the actionof the knivestfi and fia. I The upper-trimming means-841s supporteda-carrier94 which is fast on apostfifi: mounted for. vertical movements:and for turning move- 1 ments in'the frame ofthe machine, this postbeingmoved downwardly by-fluid pressure means (notshown) to earrytheupper-trimming means toward the wipers prior to its action onthe upper.is limited by a stop member '98 which is adjustable upwardly anddownwardly under the lower end of the post by means fully described inthe previously mentioned application. This adjustment is such as toposition the cutting edges of theknives 86-and 88; when they operate onthe upper, in-a plane spaced-from the top faces of the wipers a-distancesubstantially equal to the thicknessof the outer layer of the uppermaterials, sothat the knives, moving in directions. parallel to thosefaces,.will remove the other layers while leaving the margin of theouter layer to be wiped inwardly-over the insole. In accordance with thedisclosure of Letters Patent No. 2,337,558, granted onDecember 28, 1943,on an application of mine, and alsowith the disclosure of the previouslymentioned application, provision isafiorded after the uppertrimmingoperation for the gripping and pulling of the upper a second time by thegrippers, in engagement at this time onlyv with the outer layer of theupper materials, and for the wiping of the upper heightwise of the lasta second time by the toe former coordinately with the second pull on theupper (Fig. 9) In proper time relation to these operations the carrier94 is moved upwardly to carry the upper-trimming means away from theshoe and is swung about the axis of the post 96 to carry cement-applyingmeans I00, also supported thereon, to a position over the toe end of theshoe, after which the carrier is moved downwardly to carry thecement-applying means into engagement with the insole and to applycement thereto. Thereafter-the margin of the upper is wiped inwardlySuch downwardmovement of the post over the insole bythe wipers "I4 intoposition; to

besecured to-the insole by thecement.

In general accordance with the disclosure of Letters Patent- N0.2,479,575, the wiper support 82 is moved upwardly to carry the-wipersand'the toe former-heightwise of the shoe as above described by a pairof pistons I92(Fig. 2) vertical- 1y movable in cylinders Iii fast on theframe-of the machine, the pistons being moved upwardly byfluid admittedto=t-he lower ends of thecylinders. The pistons Hi2. are arranged to actrespectively on the opposite side-portions of the wiper'support throughconnections which, for a purpose hereinafter'described, are herein shownas differently constructed at the opposite sides of the supportrespectively. Associated with the left-hand piston I02'is a link [I16(Fig.6) pivotally mounted on a pinIGfi-in thewiper support and providedatits-lower end with a slot III] through which extends a-pin II2 mountedinan upwardextension of'the piston. Associated with the right-handpiston is a differently formed link IHII (Fig. 5) ia'ston a'shaft- I I6in-the wiper support and provided with a slot H8 through which extends apin I29 mounted'in an upward extension of the piston. Disregarding forthe moment the diiierences betweenthe links lflfiand I I4, it maybestated that as'the pistons I02 are moved upwardly the pins I'I2'and I20engage. the respective links I66 and I I4 and thereby raise the wipersupport, these movements of the pistons being limited by meanshereinafter described. When the wipers are operated to-wipe the marginof the upper inwardly over-theinsole, the slots in the links permit thewiper support andtheparts thereon to be moved independently of the'pistons somewhat farther against theforce of gravity in response toresistance of the margin of the upper to the movements of thewipers-,-;so-that the wipers-will not acttoo severely on portions of themargin of the upper in wiping it inwardly,

especially if the bottom of'the toe end of thel-ast hasa convexcurvature.

After the wipershave wiped the margin of the upper inwardly, it isdesirable'to increase their downwardpressure thereon. For this purpose,in accordance with the disclosureof the lastmentioned Letters Patent,theupper portions of the pistons I02 are of reduced'diameter and areslidably movable in sleeves I22 which are secured to the upper-ends ofthe cylinders I04 and extend downwardly within the cylinders, the

sleeves having thereon upwardly extending lugs I25 which engage the pinsH2 and I2!) to limit downward movements of the pistons. Between thelowerend of each sleeve and the larger portion of the piston IE2 isan annularchamber I25 into which fluid is-admitted at the proper time from a pipeline I26 (Fig. 11) under control of a valve I27 to cause the wipers toapply increased downward pressure on the margin of the upper, the lowerends of the cylinders at this time being open to exhaust. In thisoperation the pins H2 and I20 act on the links I06 and I It at the lowerends of the slots in the links. Before the wipers are withdrawn fromover the shoe bottom the pressure is terminatedin the chambers I25 andis applied again below the pistons to relieve the pressure of the wiperson the margin of the upper. After the Wipers have been withdrawn thelower end of the cylinders are again opened to exhaust to cause thewiper support to be lowered by gravity. To limit the upward movements ofthe pistons, including the movements whereby they relieve the pressureOf'the wipers on the upper as above described, their reduced portionshave thereon flanges I28 of slightly smaller diameter than the interiorof the cylinders for engaging the lower ends of the sleeve I22. It maybe further stated that, in accordance with the disclosure of thepreviously mentioned application, the machine herein shown is providedwith means for partially counterbalancing in a yieldable manner theweight of the wiper support 82 and the parts thereon when the wiperswipe the margin of the upper inwardly over the insole, such meansincluding pins I30 subjected through springs I3I to pressure of thefluid in the lower ends of the cylinders I04 and arranged to engage thelower ends of the links I06 and H4.

Machines such as that to which the invention is herein shown as appliedhave heretofore been so constructed and adjusted that, as the result ofthe upper-trimming operation, a margin of about an eighth of an inch inwidth has been left on the inner layers of the upper materials tooverlap the bottom face of the edge portion of the insole when thewipers are moved inwardly. That is, the upward movement of the wipersupport 02 has been so limited reltaively to the position of the shoethat the top faces of the wipers have been positioned in theupper-trimming operation at the proper distance higher than the edge ofthe toe end of the insole to cause the upper-trimming means, whenproperly adjusted relatively to the wipers, to leave a margin of thatwidth on the inner layers of the upper materials beyond the edge of theinsole. When the wipers are thereafter moved upwardly again to the sameheight in time relation to the second pull applied to the upper by thegrippers, they are in the proper relation to the edge of the insole towipe the upper inwardly over the insole. Some manufacturers, however,prefer that a margin of somewhat greater width be left on the innerlayers of the upper materials to overlap the insole, although still ofconsiderably less width than the inwardly wiped margin of the outerlayer of the materials. If the wipers are moved upwardly the first timeto such a height as to provide for such increased width of margin on theinner layers, they should not be moved to the same height the secondtime, since in that case they would be too high relatively to the edgeof the insole to wipe the upper most effectively inward over the insole.The machine herein shown is accordingly provided with means whereby thewiper support 82 is moved upwardly the first time to position the wipersat the proper height to cooperate with the trimming means in providing amargin of the increased width on the inner layers, but is moved upwardlythe second time to a position a little lower than the limit of its firstupward movement to position the wipers in proper relation to the shoefor wiping the upper inwardly over the insole. For this purpose the slotH8 in the link II4 associated with the right-hand piston I02 is soformed that the upper wall of the slot has a rear portion a which isstepped upward a short distance relatively to a front portion b thereof.Initially the portion b is engaged by the pin I20, and by suchengagement the wiper support is moved upwardly to the greater heightrequired for the trimming of the upper in the manner above described.The slot I I in the link I associated with the left-hand piston I02 isso arranged that initially the pin I I2 is slightly below the upper endof the slot, as shown in Fig. 6, thus providing for lost motion beforethe left-hand piston becomes effective in raising the'wiper support.When the two pistons I02, moreover, are at the limits of their upwardmovements the pin I I2 is positioned the same distance as initiallybelow the upper end of the slot in the link I06, the right-hand pistonalone, therefore, being effective on the wiper support at the end of theupward movement of the support. To cause the wiper support to be movedupward the second time to a position short of the limit of its firstupward movement, the link H4 is swung in a clockwise direction withreference to Fig. 5 to position the stepped-up Wall a of the slot I I8over the pin I 20. For this purpose there is pivotally mounted forswinging movement about a pin I32 in a fixed casting I34 a latch I36held initially by a spring I38 in a position determined by itsengagement with a'shoulder I40 on the casting. After the first upwardmovement of the wiper support but prior to its second upward movementthis latch is swung against the resistance of the spring to a positionin which its upper end is over a roll I42 mounted on a rearwardlyextending arm I44 which is fast on the shaft IIii to which the link II4also is secured. This movement of the latch i effected by a piston I46mounted in a cylinder I48 formed in the casting I34, the rounded frontend of the piston engaging the latch. Conveniently the cylinder I48 isin communication with a pipe line leading to means, not herein shown,for swinging the carrier 94 (Fig. 1) to carry the upper-trimming meansaway from over the shoe, since this movement of the carrier takes placeat the time when it is desired to operate the latch. The latch havingbeen swung to a position over the roll I42, it serves to swing the linkI I4 as above described in response to the second upward movement of thewiper support. The link is thus swung against the resistance of a returnspring I50 connected at its lower end to the arm I44 and at its upperend (Fig. 2) to a clip I52 secured to the wiper support/ By reason ofthe stepped-up position of the portion a of the wall of the slot II8 thepin II2 carried by the left-hand piston I02 also is effective on thelink I06 associated therewith substantially throughout the second upwardmovement of the wiper support.

Pivotally connected at its rear end to the latch I36 is a link I54provided in its front end with a slot I 56 into which extends a pin I58mounted in a lever I60, this lever being mounted to swing about a pinI62 supported by one of the cylinder castings I04. Connected to thelever is a spring I54 which under the conditions illustrated holds it ina position determined as hereinafter described. Connected to the upperend of the lever is a latch I66 extending forwardly through an openingI68 in the frame of the machine and having a hook-shaped front end bywhich the operator may swing the upper arm of the lever I60 in a forwarddirection against the resistance of the spring I64, the latch beingprovided with a shoulder I I0 arranged to engage a plate I I2 on theframe to hold the lever in the position to which it is thus moved by theoperator. By its forward swinging movement the upper arm of the leveracts through the link I54 to swing the latch I36 to a position over theroll I42, in which position the latch I36 remains as long as the leverI60 is held by the latch I66. The link I I4, therefore, is swung by thelatch I36 in the manner above described in response to every upwardmovement of the wiper support, and accordingly the wipers are movedupward the first time only to the same height as the second time. It

sesame ll willbe evident that under'these conditions the upper trimming'means 84 must occupy in the upper-trimming operation a correspondinglylower position in order to cooperate properly with the wipers intrimming the upper, thereby providing a margin of less Width beyond theedge of the insole on the inner layers of the upper materi'als.Provision is therefore afforded for determining, by the movement of thelever I60, a lower limit of downward movement of the carrier 94 whichsupports the upper-trimming means. Supported on the top of the stopmember '96 (Figs. 1 and 7), previously described as arranged'to engagethe lower end of the post 96 t'o-limit downward movement of the carrier94, is' 'an-auxiliary stop' member I It pivotally mounted to swingabout'a' stud I'IB'into or out of position for'limiting engagemnet withthe lower end of the post. 'Asshown in Fig. 7 the auxiliary stop memberis in position thus to engage the post, this being its position when thewipers are moved to the greater height and the trimming means acts toprovide a margin of greater width on the'inner layers of the uppermaterials. Pivotally'fconnected to the lower end of the lever I is-arearwardly extending link I18 which is pivotally connected at its rearend to an arm I fast on a short vertical'shaft I82 rotatable in theframe, this shaft having also fast thereon an arm I84pivota1lyconnected'to one end of a link I66 the other end of which ispivotallyconnected to an arm I88 on the auxiliary stop member I'M. When the leverI66 is swung to the position determined by the latch'I6'B it actsthrough the connections described to swing the auxiliary stop member'I'M to an idleposition where it will have 'tion corresponding to thelower position of the wipers at that time. When the auxiliary stopmember I'M is in its operative position it engages a"member I96 which ispart of a ball bearing shownin thepreviously mentioned application asresting on the stop member 98, the member I90 accordingly limitingthemovement of the lever I50 under theinfluence of the spring I64. When thelever I66 is in the position shown it is not disturbed by the movementof the latch I36 by the piston I-46' by reason of the slot I56 in thelink I54. The movement of the latch by the piston is limited byengagement of a projection I92 onits lower end with a top face of thecasting I34. Located above the auxiliary stop member I'M'is anothersimilar stop member I94 which is also mounted to swing about the studI16 and in accordance'with the disclosure of the previously mentionedapplication may, if desired, be

swung to a position under the post 96 to prevent the upper-trimmingmeans from being carried downwardly far enough to operate on a shoe.

To facilitate the return of the link I I4 by the spring I50: in responseto each downward movement" of the wiper support 82 after the action ofthe latch I36 on the link, there is threaded in a member I carried bythe wiper support a screw IQBthe head of which is arranged to engage theleft-hand cylinder casting I04 and thereby to limit the downwardmovement of the wiper support. This screw is so adjusted that when thewiper support is at the limit of its downward movement the pin I20is'only lightly in contact with the portion 19 of the'upper wall of'theslot M8, the screw serving to relieve the pin fromi such'pressure of thelink thereon as might cause spring.

'It will be evident that the greater upward movement of the wipersupport the first time than t'he'second time extends and increases thewiping effect of'the toe former I6 on portions of the upper adjacent tothe extreme'edge of the insole. This has been found to contributeappreciably to the smoothness of the upper in thislocation in thecompleted shoe.

Associated with the right-hand piston I62 ismechanism, including aspring 206' (Fig. 1), for. supplementing the pressure of the fluid inforcing" the wipers more-firmly down on the overwiped margin of theupper, this mechanism being provided to permit a variation in the forcethus applied by'the wipers to the upper. This mechanism'is of the sameconstruction as disclosed in Letters Patent'No. 2,479,575; and thereforewill not be described in-detail. In the construction herein shownadditional means is provided for efiectinga further'variation in thedownward pressure applied by the wipers to the upper. For this purposethe pipeline I26 (Fig. 11) is so arranged as to conduct fluid from themanifold always to the chamber I25 in the left-hand cylinder I0 when thevalve I21 is operated, but has therein a valve 2G2 which may be rotatedby a handle 26 to a' position such as to prevent flow of the fluid tothe chamber I25 in the righthand cylinder. With the valve in theposition shown there is a passage for-the fluid to this chamber as well.a to the chamber in the lefthand cylinder, but it will be evident thatupon rotation of the valve 'ina clockwise direction with reference toFig. 11 through an arc of 90 flow of the fluid to the chamber in theright-hand cylinder will be interrupted and this chamber will be put incommunication with a pipe 206 leading to the sump I8. Accordingly, thewipers may be forced downwardly on the margin of the upper by the forceof the fluid acting on both pistons I02 or onone. of the pistons alone.It'will be understood that this controlling means does not prevent suchfurthermore precise variation in the pressure applied to the upper bythe wipers as may be effected by the-above-mentioned mechincrease thispressure, no actual lifting of the wipers by the pistons can take placeuntil after one,at least, of thepins H2, I20 has engaged thecorrespondin link- I 06 or I It at the upper end of the slot formed inthe link, and that in any event the wiperswill not be raised beyondthepositions-ocupiedat the beginning of the wiping operation, in" whichthey are shown'in'Fig. 9 since the portion a of the wall of the slot IISwill at this time be over the pin I20. The machine herein shown isprovided with means whereby the wipers are raised to a higher plane thanin Fig. 'prior to their retractive movements from over the shoe bottom,thussubstantially or completely'releasing the overwiped'margin of theupper from the pressure of the wipers thereon. For the purpose" in viewa' bracket 208 is secured on the front of the left-h'and portion of thewiper support -82 and-has pivotally mounted thereon a lever 2M one armof which is provided with a lug 2 I2 extending upwardly to a position infront of the forwardly and rearwardly movable wiper carrier 80 and aportion of the other arm of which extends rearwardly and is providedwith a downwardly extending lug 2M arranged to engage the left-hand endof the pin IIZ carried by the left-hand piston I02, as illustrated inFig. 2. Extending forwardly from the wiper carrier 33 through an openingin the lug 2I2 is a rod 2I6, and mounted on this rod between the wipercarrier and the lug is a spring 2E8 which is compressed by the forwardmovement of the wiper carrier in operating the wipers. Through thisspring, therefore, the lug M4 on the left-hand arm of the lever 2H] ispressed against the lefthand end of the pin I I2. Formed in this end ofthe pin is a notch 220, and when the left-hand piston is moveddownwardly to increase the pressure of the wipers on the upper thedownward movement of the pin H2 along the slot Ilii (Fig. 5) in the linkIE6 before the piston becomes effective on the wipers causes the lug 2I4on the lever 2m to enter the notch 220 in the pin. When the left-handpiston H32, therefore, is moved upwardly to relieve the pressure of thewipers on the upper there is substantially no lost motion of the pin II2 in the slot I It, the pin acting through the lever Elli on the wipersupport to impart to the support an upward movement substantially equalto the upward movement of the piston before the piston is stopped by thesleeve I22. The wipers, therefore, are raised to positions such as toapply substantially no pressure to the upper, as illustrated in Fig. 10.An important advantage of this will be understood from the fact that thetiming of the valve 25 is, as heretofore, such as to release the fluidfrom the cylinder 8 and thus to cause return movement of the toe rest dprior to the retraotive movements of the wipers from over the shoe. Ithas already been explained that any force applied to the shoe tending topress the shoe more firmly on the toe rest tends to hold the cut-offvalve 58 of the pressure-controlling means 44 associated with the toerest more firmly closed. Unless the shoe, therefore, is substantiallyreleased from the downward pressure of the wipers thereon before thevalve 29 is moved to exhaust position, the cut-off valve 58 may not openand release the fluid from the cylinder 8 notwithstanding such movementof the valve 2t. Raising of the wipers in the manner described insuresthe prompt withdrawal of the toe rest at the time intended. When thewiper carrier 88 moves rearwardly to retract the wipers, a head 222 onthe rod 2I6 engages the lug 212 near the end of that movement of thecarrier and thus withdraws the lug M4 on the lever 2 I Hi from the notch22% in the pin I I2.

Also secured to the front of the left-hand portion of the wiper support82 is a bar 224 in which is mounted a screw 226 in position to engagethe wiper carrier 80 and thereby to limit the forward movement of thecarrier. This screw, therefore, serves to determine adjustably thelimits of the inward movements of the wipers over the shoe bothlengthwise and widthwise of the shoe.

Since the manner of operation of the mechanisms described has alreadybeen fully explained in connection with the description of themechanism, no further description of the operation of the machine isnecessary.
